I have a large shed with 6" x 3" timber uprights resting on a stub
block wall. The bottom 2-3 feet of the posts is rotten so I want to
splice-in some new timber. I can't think how to cut a decent lap joint
in the bottom end of the remaining upright so I'm tempted to butt join
the timber and add steel plates (fish plates?) on each side - at a
guess these would be around 150 wide 450 long and a few mm thick.

Suggestions welcomed for how to cut a lap joint on the bottom of a bit
of timber that's waggling in the breeze, or for a source of suitable
steel plates.

Bit of care with a decent handsaw? 3" with a jigsaw is tricky.
Trying to do this with a jigsaw would be more than tricky - a waste of time!

I would strengthen by screwing on some 25x50mm folded galvanised steel
(because I have some:-) but 1"x2" angle would do. Use two lengths per join.

Alternatively the agricultural approach... butt join and then strengthen
by nailing on 3"x2" either side:-)
